Thulium laser operation o the 3H4 - 3H6 transition at 823 nm has been demonstrated in bulk TmYAG by quasi-cw pumping with a fiber-coupled diode array at 782 nm. Prior demonstration of this laser transition have been limited primarily to fluorozirconate glass host materials in waveguide configurations. Population trapping has been identified as an important consideration in the design and operation of lasers on this transition. The use of a crystalline host should enable both high peak and average power operation, and the basic principles discussed here should be extensible to other crystalline hosts and to room temperature operation.
